He said that concrete steps were agreed following a meeting on Monday in which German Transport Minister Andreas Scheuer questioned Daimler boss Dieter Zetsche over how many Mercedes-Benz vans and cars need to be fixed after a regulator found illegal software in one of its models.

The ministry was asked to comment on a report in magazine Der Spiegel that said Scheuer had threatened to fine Daimler 3.75 billion euros ($4.38 billion) over a diesel emissions scandal.
